It's real easy if you get Robert and Zachary to do it for you, which I can tell you, is what Gary is going to do. This is a shot of the guys replacing mine, Gary is the guy in the white shirt, doing what I am doing, WATCHING.
From what I remember from mine, the instructions are written for someone who already knows what they are doing. It is not impossible for the average person, but there are a few specialty tools you need - no big deal. The REAL instructions are in the service manual - but you are WAY better off watching the youtube videos by Paul Diger, Greg Pylant and Marc Mathern. (All past forum members)

Robert's girlfriend lives in California, he is out there a lot, just sayin.........................................
